Fulcrum Speed 55 DB Disc Carbon Wheelset

SPEED 55 DB

The model therefore focuses on a demanding and “racing” audience. To improve the rolling resistance (and ultimately the speed) of the wheel/tyre system, we designed this model in the 2-WAY FIT version.

The manufacturing process of the carbon fibre rim without holes in the internal channel – a patented construction technology – also allows a stronger and sturdier construction capable of withstanding even the most extreme racing conditions.  The rim with a 19 mm inner width perfectly matches recent trends of using increasingly wider tyres – a choice that further improves the aerodynamic performance of the wheel/tyre system.

This data has been validated by intensive wind tunnel studies and trials where new projects are tested on a regular basis. SPEED 55 DB proved to be the best option in terms of aerodynamic penetration indexes in the Fulcrum range and is derived from the profiles developed for the tubular version used by World Tour teams.

The SPEED range not only responds in terms of aerodynamic performance. Optimizing performance also requires the wheels to be light and run smooth. The scale stops at 1580 gr and we have chosen to add ceramic USB bearing components.
